Do Hypoallergenic filters lower the output pressure in a ResMed S9 - LesPauloholic - 05-04-2015

Hi,

I'm new here and have been reading and researching a lot. I seem to remember reading somewhere that hypoallergenic filters can cause the output pressure to be lower than what the machine readout says it is, but now I can't find where I read that.

Has anyone experienced that? Do you know where I might have read that?

Thanks,
LesPauloholic

Welcome to the forum.

As far as I know, the pressure sensor is on the output side of the blower. Hypoallergenic filters shouldn't have any effect on output pressures.

Hi LesPauloholic,
WELCOME! to the forum.!
I don't notice any problems with my pressure using a hypoallergenic filter.
Hang in there for more responses to your post and much success to you with your CPAP therapy.

Shouldn't.

LesPauloholic ,

I am going to install one tonight on my new S9 Autoset. The filter would only cause a very subtle pressure drop IF the flow rate was very high. I would put the filter right at the output of the machine since this is the lowest "impedance" point, not near your mask. I prefer to breath the cleanest air possible due to my allergies. If anyone if interested I can measure the pressure drop at the highest flow rate that the machine is capable of producing. Jay

That probably apply to the antibacterial filters, not to hypoallergenic or standard filters

Hi zonk, you are correct, my mistake, I use an antibacterial filter! Jay

IIRC, There is a setting in the S9 for the antibacterial filter.

No such setting to my knowledge, the only setting to do with filters is a reminder option when to replace the filter but got nothing to do with the antibacterial filter

According to ResMed "Antibacterial filters are not compatible with the ClimateLine, ClimateLineMAX or SlimLine tubing but can be used with the Standard air tubing". Also ResMed warn "Blocking the air tubing and/or air inlet of the S9 device while in operation could lead to overheating of the device.
